I think the big difference with Rybka is that it probes the critical lines better than other engines at the moment. It will especially probe a pawn push and look deep into the consequences of how this pawn push can be exploited and protected deeper than the other engines. Another thing I notice is that when there is no clear strong move, it will follow classic strong chess guidlines such as putting rook on open file, loading more pieces onto an attacked king. You cannot underestimate the strength of a properly configured search function. If you search only the critical lines and don't waste cpu cycles on second or third rate moves, you will have a multiplier effect on the strength of your hardware. Any experienced chess player knows that if you feel you have an advantage the best thing is to hold off a quick liquidation of your advantage because loading the position with strong solid moves usually pays much higher dividens. Most other engines seem to prefer to liquidate and keep a small advantage if their search doesn't show a bigger advantage further down into its search.
